Duplicate address detection is around for a reason, and also applies here. By means of the V-octet, seeking to "appropriate" a part of all v6 address space for 4rd, or any other device class to deal with a remote case of a duplicate, which may still happen, seems overdone. In any case this looks to be a 6man consideration. -Woj. > >RD > > > > > > >> >> gomlefisk: otroan$ sudo ifconfig en1 inet6 2001:db8:0:0:0300::1/64 >> gomlefisk: otroan$ ifconfig en1 >> en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1400 >> ether 00:26:bb:1a:77:2e >> inet6 fe80::226:bbff:fe1a:772e%en1 prefixlen 64 scopeid 0x6 >> inet 10.147.112.88 netmask 0xfffffc00 broadcast 10.147.115.255 >> inet6 2001:db8::300:0:0:1 prefixlen 64 >> media: autoselect >> status: active >> gomlefisk: otroan$ >> >> cheers, >> Ole >> _______________________________________________ >> Softwires mailing list >> [email protected] >> https://www.ietf.org/mailman/listinfo/softwires _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
